Board Thread:Pokémon Help/@comment-34115345-20180102044325

Hey, so I was wondering if you guys could help me out with my team and what to add, what to replace, and things like that for anything, like the item, a move, or even the Pokemon itself. If a Pokemon has a bad nature please tell me which nature I should try to find for it. If you see a Pokemon weak on the team please tell me which and what I should replace it with. So anyway, here is my team(Oh and btw they are all max level, none are shiny or hidden ability) :

Salamence: Item: Firizium Z, Nature: Lax, Moveset: Crunch, Zen Headbutt, Flamethrower, and Dragon Claw.

Charizard: Item: Charizardite Y, Nature: Relaxed, Moveset: Flamethrower, Flare Blitz, Fly, and Solar Beam

Ash-Greninja: Item: Waterium Z, Nature: Mild, Moveset: Power-Up Punch(Just using that until I have enough BP to get Ice Beam), Hydro Pump, Grass Knot, and Dark Pulse.

Tyranitar: Item: Tyranitarite, Nature: Lonely, Moveset: Stone Edge, Dark Pulse, Earthquake, and Power-Up Punch.

Dragonite: Item: Dragonizium Z, Nature: Calm, Moveset: Brick Break, Dragon Rush, Aqua Tail, and Steel Wing.

Gengar: Item: Gengarite, Nature: Rash, Moveset: Shadow Ball, Hypnosis, Destiny Bond, and Thunderbolt

...and that's it. Thank You if you read this and commented how to help me out! Also just for fun, when do you think the 8th Gym is gonna come out? Oh, also what does Bottle Cap do?
